Application filed October 15, 1921.A Serialv No. 507,981.

To a/.ZZ whom t may concern.'

Be it known that I, ALONZO D. FAUSETT, a citizen of the United States, residing at TWaterloo, in the county of De Kalb and State of Indiana, have invented certain new and useful Improvements in Superheaters for Autos, of which the following is a specification.

rlhis invention has relation to certain new and useful improvements in a superheater of air and steam mixture for automobiles and has for its primary object the provision of a device of the character stated which may be readily incorporated in any automobile structure of conventional form and will serve to utilize exhaustl gases from the engine to heat a liquid such as water and cause vaporizing of the same as it is fed to theintake manifold to pass into the cylinderswith the mixture from the carburetor, thereby improving the quality of the'mixture as it is fed into the cylinders and permitting a more ready combustion of the mixture.

The invention has for another object the provision of a device of the character stated which will be of extremely simple and inexpensive construction as .well as highly efficient in use and composed of the minimum number of parts and in which the amount of water and ail to be fed in vapor form to the intake manifold may be readily regulated, as desired.

lith the foregoing and other objects in view as will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement lof cooperating elements as hereinafter more specifically set forth. claimed and shown in the accompanying drawings forming a part of the present application and in which Figure 1 is an elevation of a portion of an engine of conventional type with my invention applied thereto. y

Figure 2 is a detail section view on an enlarged scale through a portion of the present device. y

Fig. 3 is a transverse vertical section through the sight-feed attachment. y

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 indicates in general an engine for a motor vehicle or the like having surnam-:Arran Foa AUTOS.

the usual intake manifold with the carburetor 3 connected thereto and the exhaustmanifold 4 from which the exhaust gases are carried from the cylinders lof the engine.

ln Fig. 1 of the drawings a portion of the usual dash board 5 of the motor vehicle has been indicated so as to show properly poist` sitioned thereon the vfluid tank 6 for coni taining water or the like and from` which the small tube 7 depends, said tube-7 lbeing extended at an angle and preferably; passed through the dash board or other support 5,

shown at 8 and finally extended forwardly,- shown at 9 and connected with the intake manifold '2., forwardly of the carburetor 3, as shownvclearly in Fig. 1 of the drawings. On the straight upper portion of the small tube 7 a double valve 'casing 10 is mounted and an upper liquid controlling valve 11 is carried in the valve casing `10 at a point above the sight opening and air inlet 12, which latter extendsthrough the casing 10. A second or air controlling'valve 13 is carried by the valve casing 10 below the open ing 12 so as to regulate the quantity of air entering the tube 7 to mix with the liquid passing from the tank 6. y

Enclosing the greater portion of the horizontal forward end of the small tube y7, is the casing 14 having connected therewith the pipe 15 leading from the exhaust manifold 4 so as to employ'the heat of'exhaust gases to heat the mixture of water and air as it passes through the section 9 of the tube 7 to the intake manifold 2. While the cas` ing 14 may be of any preferred construction, I have shown the same as being composed of a pair of sections of a diameter considerably greater than the exterior diameter of the tube 7 so as to form a chamberaround v' the same. The opposite ends of thecasing sus 14 are shown as being closed bythe cap t central coupling 17 with which the pipe 15,l

previously 'mentioned is. connected. This f provides for a secured connection between theparts of the casing 14 and the pipe 15 and it will be understood that the flanges on the outer ends of the caps. 16 will limit
